Cold and drought resistant fertilizer

Phosphate fertilizer is used as a cold and drought resistant fertilizer.

Phosphate fertilizer, the full name of phosphorus fertilizer, is a fertilizer with phosphorus as the main nutrient, which can make plants resistant to cold and drought. Phosphorus is a component of cell protoplasm in plants and plays an important role in cell growth and proliferation. Phosphorus is also involved in photosynthesis, the utilization of sugar and starch, and the transfer of energy in plant life processes.

When phosphate fertilizer is applied in an appropriate amount, it can promote crop tillering and early maturity, enhance its cold resistance, and increase its yield and quality. Phosphate fertilizer can also promote the growth of plant root systems in the seedling stage and make plants mature earlier. When plants produce fruit, a large amount of phosphorus is transferred into the grains, making the grains plump.

Rational application of phosphate fertilizer can increase crop yield, improve crop quality, accelerate the tillering of cereal crops and promote full grains; promote the flowering and fruiting of cotton, melons, solanaceous vegetables and fruit trees, and increase the fruiting rate; increase Sugar content in beet, sugar cane, watermelon, etc.; increases oil content in rapeseed.

Precautions for fertilization in high temperature and drought weather

1. According to the physiological growth and development process of plants and the critical area of ??crop fertilizer demand, timely and effective top dressing should be adopted. If there is growth, apply fertilizer; if there is little growth, apply less or no fertilizer. If the growth is large, apply more (but not too much). The stages that require fertilizer are the vigorous growth, flowering and fruiting stages of crops.

2. On the one hand, phosphate fertilizer can be used more effectively at higher temperatures and produce good fertilizer efficiency. On the other hand, sufficient phosphorus and high-quality Trim phosphate fertilizer can improve the utilization rate of nitrogen. To nourish nitrogen with phosphorus. Since carbon ammonia is easy to decompose when heated and high-concentration nitrogen fertilizers can easily cause crop seedling burning, the amount of nitrogen fertilizers should be reduced in hot and dry weather.

3. The fertilization method is to apply it deeply, dilute it and then add it with water. Greenhouse planting requires integrated spraying of water and fertilizer, or drip irrigation. No matter what method you take, you must keep a distance of more than 10 centimeters from the plants to prevent fertilizers from directly contacting the plant straw and burning the seedlings. Especially peppers, flue-cured tobacco, melons, and vegetable crops.

4. High temperature and drought. In weather with high temperature above 35℃ at noon, top dressing is generally not recommended. Fertilization time is in the evening, which is not only suitable for personnel operation, but also can make up for the shortcomings of crop absorption time.
